Graphic integral
--- Introduction ---

This module is an exercise on the graphical recognition of
the integral of a function.

The server will give you the curve of a continuous function f
on the interval . This function is randomly generated
by the server, and its expression is hidden from you. You will then be presented
with a certain number of other curves, and have to recognize among them that
of an anti-derivative function , (or one of ,
or ,
according to the configuration of the exercise). To send the reply, you
can simply click on the curve which you think is the good one.
